testcontainers wait indefinitely without effects when running in Gitlab-CI

I’m running a test based on testcontainers-python in a container running in Gitlab CI.

Basically the CI spawns a docker-in-docker container next to the container running the tests. I then set the environment variable DOCKER_HOST so that it can be used by testcontainers.

But in practice the test just get stuck, so I ran it with pytest -s to see the logs of testcontainers and got:

tests/test.py
Pulling image postgres:10
Container started:  4a1115dc98
Waiting to be ready...

And then it gets stuck indefinitely (I waited 20 minutes).

For the record, testcontainers-java works perfectly with this same situation, so it should be possible to make this work.

I’m not sure how I can get more debug information to understand what is happening, but shouldn’t it timeout normally at least?

Fixed in #85. Feel free to reopen if problems persist.

@willgme happy to hear that it resolves your issue. To be merged, we need to refactor some codes to pass the all test cases and test on windows and other DinD environments. I just don’t have time these days
